Touch Detector TTP223E-BA6 SOT23-6 Single Channel Touch Keys Sensor Chip
Description
The TTP223E-BA6 TonTouchTM is a touch pad detector IC which offers 1 touch key. Stable sensing method can cover diversity conditions. The touching detection IC is designed for replacing traditional direct button key with diverse pad size. Low power consumption and wide operating voltage are the contact key features for DC or AC application.
Feature
- Operating voltage 2.0V ~ 5.5V
- Operating current, @VDD=3V no load
- At low power mode typical 2.0uA, maximum 4.0uA
- The response time max about 220mS at low power mode @VDD=3V
- Sensitivity can adjust by the capacitance(1~50pF)outside
- Stable touching detection of human body for replacing traditional direct switch key
- Provides Low Power mode
- Provides direct output or toggle output selection by pin option (TOG pin)
- Q pin is CMOS output can be selected active high or active low by pin option (AHLB pin)
- After power-on have about 0.5sec stable-time, during the time do not touch the key pad, and the function is disabled
- Auto calibration for life
- The re-calibration period is about 1 sec within 8 sec after power-on. When key has been
- touched within 8 sec or key has not been touched more than 8 sec after power-on, then the
- re-calibration period change to 4 sec
